摘要

A light source at the University of Wisconsin-Madison will close on 7 March, following a US National Science Foundation (NSF) decision to cut off its funding. The Synchrotron Radiation Center has provided researchers with infrared, ultraviolet and X-ray photons for experiments including semiconductor research and biological imaging since 1986. The NSF cut support in 2011 because of budget constraints (see Nature 471,278; 2011).
